Hey everyone! Here are our meeting logs: http://meetbot.debian.net/tor-meeting/2023/tor-meeting.2023-09-21-15.57.html And our meeting pad: Anti-censorship work meeting pad -------------------------------- ------------------------------------------------------------------------------------ THIS IS A PUBLIC PAD ------------------------------------------------------------------------------------ Anti-censorship -------------------------------- Next meeting: Thursday, Sep 28 16:00 UTC Facilitator: onyinyang Weekly meetings, every Thursday at 16:00 UTC, in #tor-meeting at OFTC (channel is logged while meetings are in progress) This week's Facilitator: Shelikhoo == Goal of this meeting == Weekly check-in about the status of anti-censorship work at Tor.

(The hypothesis being that the captcha API is the primary way that they discover bridges.) * A proposal to phase out captchas in bridgedb from 2021: https://lists.torproject.org/pipermail/tor-dev/2021-July/014602.html * Replies suggested doing an experiment with captcha removal for 50% of bridges, that way they don't all get burned if it doesn't work * https://lists.torproject.org/pipermail/tor-dev/2021-July/014603.html * https://lists.torproject.org/pipermail/tor-dev/2021-July/014604.html * agreement on removing the in-house captcha * meskio will create an issue to explore captcha experiments * https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/176 * snowflake domain front resolving to a mix of fastly and cloudflare since 2023-09-20 * https://lists.torproject.org/pipermail/anti-censorship-team/2023-September/… * https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42120 * options for remediation: * change the domain front to one that still always resolves to fastly * not a lot of good options, also we don't have good knowledge of which are already censored https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * locally pin the IP address of the front domain we are using now * or resolve a different (fastly) name, but keep using the same front that we use now * creates an inconsistency between DNS and TLS * we can change the front domain for circumvention settings users, which does not require waiting for a TB/orbot/etc. release * change the domain to foursquare.com * guardian project / orbot? meskio says orbot is already using circumvention settings. But circumvention settings might be ignored for built-in bridges. * dcf will make a forum post and contact guardian project * community team will try to get testing of fourquare.com in the next week * meskio will make the change in Tor Browser and circumvention settings * Remove Go 1.20 support? kcp library seems to crash compiler: * https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * # github.com/xtaci/kcp-go/v5 * /go/pkg/mod/github.com/xtaci/kcp-go/v5@v5.6.3/timedsched.go:19:6: internal compiler error: panic: interface conversion: interface is nil, not ir.Node * Please file a bug report including a short program that triggers the error. * https://go.dev/issue/new * note: module requires Go 1.21 * https://github.com/xtaci/kcp-go/blob/v5.6.3/timedsched.go#L19 * Go compiler issue: https://github.com/golang/go/issues/61074 * Has to do with new compiler builtin "clear" in go1.21 https://tip.golang.org/doc/go1.21#language * ...which kcp-go started using 10 days ago https://github.com/xtaci/kcp-go/commit/691fc2febef3dd927dca7815b207fb4dad19… * shelikhoo will go ahead and remove go1.20 support == Actions == == Interesting links == * https://www.bamsoftware.com/papers/fep-flaws/#sec:obfs4 * writeup of Elligator distinguishers that have affected obfs4proxy == Reading group == * We will discuss "" on * * Questions to ask and goals to have: * What aspects of the paper are questionable? * Are there immediate actions we can take based on this work? * Are there long-term actions we can take based on this work? * Is there future work that we want to call out in hopes that others will pick it up? == Updates == Name: This week: - What you worked on this week.

Tor at the Global Gathering Feira
by isabela fernandes 14 Sep '23

14 Sep '23

Hello community! Many Tor people will be at the Feira, we are looking forward to hanging out with y'all soon! We will be hosting conversation circles at our Onion table :) right in front of our booth. Here is the schedule: Friday Sept 15: - 14:00-15:00 -> *How to contribute to the Tor project* -> Our welcoming circle! Come meet Tor people and learn more about the project and how you can contribute to it. - 17:00-18:00 -> *Shaping the Tor advocates program* -> We are starting to organize a “Tor advocates program” and we want to host a circle for people who train others on Tor to learn about this idea and give us feedback on it. Saturday Sept 16: - 15:30-16:30 -> *Sharing between anti-censorship tools builders* -> We would like to invite other people working on building anti-censorship tools for a circle to share and build collaboration. - 17:00-18:00 ->* Experience of censored users* -> Members of our Anti-Censorship team will be hosting a circle for users to come and share their experience using our circumvention tools so we can learn what is working and how to improve what is not working. Sunday Sep 17: - 14:00-15:00 ->* Sharing lesson on usability research / user needs* -> We made big changes at Tor to have the user as the center of everything we do. In 2017 we started to implement usability research as the key director for our decisions on development and organization strategy. We would like to share about what we learned during this process and how it has been beneficial to us. - 17:00-18:00 -> *NoScript conversation* -> NoScript is a critical piece of privacy online that every user interacts with. At this circle the creator of NoScript will be sharing information about the project’s status and future plans. We would like to invite you to join the conversation to share your feedback or ask questions about NoScript and its integration in the Tor Browser. Looking forward to seeing you! cheers, isabela

Canceling the Network Team Monday meetings on IRC
by Alexander Færøy 11 Sep '23

11 Sep '23

Hello list! After the end of Sponsor 61, the Network Team Monday meetings on IRC returned to being a simple checklist meeting that is done in roughly 10 to 15 min. in average with zero external participants. I can do the checklist items directly with people over IRC without forcing a context switch for everybody by getting them into a meeting every week. The team have for a long time wanted to cut down on meetings and the BBB format where we have focused working groups works much better after the team started having multiple projects going on in parallel instead of "just" maintaining C Tor. The team continues to be readily available both via GitLab, the tor-dev@ mailing list, and via #tor-dev on IRC. All the best, Alex -- Alexander Færøy

ebanam's monthly status report for August 2023
by ebanam 08 Sep '23

08 Sep '23

Hello everyone, We saw a uptick in user support requests from Chinese speaking users in the past month, but in general most of my work focussed on providing help to users in regions where Tor is censored. With the release of Proof of Work (PoW) defense for Onion Services[0], I also worked on gathering some initial feedback. # PoW defense for Onion Services feedback Most of the initial feedback and questions have been about (1) how it will affect user's connecting to Onion Services, (2) whether users will have to solve a captcha puzzle, and, (3) discussion about the underlying algorithm used. Following is a thorough breakdown of tickets our user support team handled in August: Timeframe: 01 - 31 August 2023 # Frontdesk (email) * 1041 (↑) RT tickets created * 942 (↑) RT tickets resolved Most frequent tickets by numbers: 1. 650 (↑) RT tickets: circumventing censorship in Russian speaking countries. 2. 284 (↑) RT tickets: private bridge requests from Chinese speaking users. 3. 1 (↓) RT ticket: circumventing censorship with Tor in Farsi. # Telegram, WhatsApp and Signal Support channel * 642 (↓) tickets resolved Breakdown: * 609 (↓) tickets on Telegram * 22 (↑) tickets on WhatsApp * 11 (↑) tickets on Signal The most frequent tickets on cdr.link have been about: 1. 393 (↓) tickets: Circumventing censorship in Russian speaking countries. 2. 16 (↑) tickets: Circumventing censorship in Chinese speaking users. 3. 16 (↓) tickets: Circumventing censorship in Farsi. # Highlights from the Tor Forum 1. Proof of Work (PoW) defense for Onion Service is released.[1] 2. "How Snowflake works?"[2] 3. EFF’s university Tor relay campaign[3] 4. New Alpha Release: Tor Browser 13.0a3 (Android, Windows, macOS, Linux)[4]. Help us test the 13.0ax series of Tor Browser for Alpha prior to the Tor Browser 13 stable release. Thanks! e. Note: (↑), (↓) and (-) are indicative if the number of tickets we received for these topics have been increasing, decreasing or have been the same from the previous month respectively [0]: https://blog.torproject.org/introducing-proof-of-work-defense-for-onion-ser… [1]: https://forum.torproject.org/t/proof-of-work-pow-defense-for-onion-service-… [2]: https://forum.torproject.org/t/how-about-snowflake-works/8710 [3]: https://forum.torproject.org/t/tor-relays-effs-university-tor-relay-campaig… [4]: https://forum.torproject.org/t/new-alpha-release-tor-browser-13-0a3-android…

Hi! This is my August'23 report! In August, I resolved 1164 tickets: On Telegram (@TorProjectSupportBot) - 496 On RT (frontdesk@tpo) - 650 On WhatsApp (+447421000612) - 11 and on Signal (+17787431312) - 7. Main lines of my work remain the same: 1. Helping Russian-speaking users download and install the Tor Browser and then resolve any issues with connecting to the Tornetwork. 2. Helping in censorship circumvention 3. Collectinguserfeedback. The most common issues I noticed during this month are: 1. Antivirus software interrupts the TB work 2. Tor for iOS - Users now need to install Onion Browser + Orbot app on their devices 3. The Tor error:"[WARN] Pluggable Transport process terminated with status code 0", which often occurs in the regions with severe internet censorship. I've also submitted a small bug found in TBA Alpha.[1] [1] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42038
